Has anyone run across a 2018-2020 F3T 16 pin connector pin out diagram? Basically the big plug under the seat that the BRP trailer harness plugs into...

I make my own harness and since we traded my RT that typically pulled the trailer in on a new F3 I need to patch in my trailer harness.

Yes, I know it's weird... but I need 6 wires instead of the usual 4 or 5... I wired up the reverse lights on our 622. Everything in the trailer is run by relays and a main, fused battery connection so no module is needed.

Thanks.
